STATIC ELECTRICITY QUIZ

Law of Attraction and Repulsion

-Things that have the same charge push each other away(they repel each other)

-Things that have opposite charges attract each other

-The total charge in a closed system is conserved! We can move the charge around, but we can’t create or destroy it

What is the difference between an insulator, conductor and semi-conductor and give an examples of each

Insulator: Do not allow electrons to move easily through them ex. rubber

Conductor: Allows electrons to move through them easily ex. aluminum

Semi-conductor: Has electrical conductivity between insulators and conductors ex. silicon

How do you charge friction, induction, and conduction?

Friction: Move electrons from one item to another different item

Induction: By polarizing an object and then leaving a permanent charge on that object by grounding it

Conduction: Transferring electrons from a charged object to a neutral one

Law of Conservation of Charge

It can be transferred from one object to another

What is discharge?

The sudden and rapid flow of an electric charge from one object to another, often creating visible sparks or arcs
